DRIVING MECHANISM. 5

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and -useful Improvements inDriving Mechanism, of which the following is a specification.

This'invention relates to the construction and organization, incombination, of various mechanical features and. devices for en portinga driving-shaft and effecting its e cient and continued lubrication; andit has for an object to provide a simple compact structure in the natureof a driving-head for supporting and lubricating that end, moreespecially of a driving-shaft, to which the power for effecting itsrotation is applied.

A driving-head constructed in accordance with the present inventionpossesses means, combined with supports, in which the shaft is mountedfor lubricating the various rubbing surfaces bya system of forcedlubrication, thecirculation of the lubricating material being preferablythrough a closed circuit. Usually there will be combined in my im- 1.proved form of driving-head with a sectional shaft a couplin device,whereby the portion or section of t e drivin -shaft from which power istaken ofi may e driven from the power-actuated section of the shaft,even though these two'sections are not.in alinement or in parallelismone with the other. A driving-head constructed and organized accordingto the present invention has, moreover,-its various mechanical detailsso combined with and related to each other that the assembling and thetaking down of. the various parts are facilitated.

'In the drawings accompanying the pres- -ent specification a drivingmechanism or head embodying the features of my present invention is setforth, Figure 1 therein illus-- trating, partly in plan view and partlyin horizontal section, such a driving-head. Fig. 2 is a longitudinalvertical section taken on the plane of the line 2 2 in Fig. 1, certainof the parts being shown in elevation, however.

In construgt ngla driving-head emb'od g e present invention. t ere willusually be a pro er sup orting-frame in which the driving-shaft wi 1 bemounted. This sup orting-frame is herein by B anrf may constitute aninte ra'l part of the frame of the mechanism, mac 'n'e, or apparatus towhich the present device plied, orit may constitute a subframese'parateand distinct from such main frame and secured thereto or affixed inplace independ- It will usually comprise a base portion, such as 2, uponwhich there is erected an upr'ight 3, having a journal portion 4,affording a bearing for the drivingshaft.

' There will preferably be provided'in the( present driving mechanism orhead an organization whereby the main section of the drivsatisfactoryturning movement, even though that portion of the shaft to which thedriving be driven with a smooth and designated is ap- 3 power is appliedis so disposed in its bearin s as to be out of alinement or out ofparalle ism with that section of the shaft from which power is taken.For this purpose the driving-shaft KOO (designated herein In a generalway b S) is sectional, the section szconstituting In this ease the onefrom which power; is taken, be-

mg mounted in the bearing portion 4 of the upright 3. The other sections, or that section to which the driving power is applied, is suitablymounted at the other or outer end of the head, the two sections beingconnected one with the other by a coupling, a suitable form of whichwill be presently described,

P designates a driving-pulley driven by a belt from a source of power,(npt herein shown,) this pulley being secured in this instance to theouter end of the driving-shaft section 3: 'In order to form a firmsupport for the section 8, the bearing, therefore, is preferablyelongated and advantageously extends some distance into the bore of thepulley P. In fact, the bearing may be so K the section-is reduced indiameter (see 5) and the pulley is attached by a key 6 to such reducedportion, being held in position against the shoulder formed by thereduced portion by the usual nut and washer 7 and 8, respectively.Ofcourse other means may be'empl'eyedf'or the attachment of the pulleyto its shaft-section.

Inorder to enable the two sections .5 and s of the driving-shaft S to bereadily coupled one-toanother and at the same time permit the section ato be supportedin a proper journal-bearing, which preferably extendssubstantially throughout its entire length, I prefer to form the bearingfor this section in adetachable'movable member, which maybe removedf'rom the head'in order to permit the assembling ofthe shaft-sectionsand their connecting-coupling; This removable or detachable member isdesi nated herein by C,

and the means for detac ably connecting it with the head may be anyappropriate for the purpose. A's constructed in this instance theattachment of the two is made by means of a so-calledinterrupted ormutilated, screw, portions of the thread 0 on the member measuredaxially thereof and extending peripherally through a considerabledistance (see thereduced sections-c) beingremoved, Whilethe bore oftheopening in the head with which the member engages is corre spondinglyformed in the usual and wellknown manner. The member C is shown'provided with a flange 9, forming a shoulder 9, preferably adapted tomake a tight joint with its contacting surface, for a reason that Thisflange may will' presently appear. have openings 0 for engagement withxaproperwrench.

Referring now to the coupling device for uniting the two sections of theshaft any construction thereof suitable for the purpose may be employed.The-form herein illustrated is in its general construction familiar tothose acquainted with such devices, although embodying certain featuresof novelty. Referring particularly to Figs; 6 to,

10, inclusive, the shaft-sections s and s are provided with respectiveheads 10 and 10', which, through an intermediate piece, are capableoftransmitting motion from one'to the other. As shown in those figures,the, head 10 is provided with a cross slot or channel 11, while the head10 is provided with a pro-. jecting feather or rib 11. Thecouplingpiece, adapted to en age, respectively, with thechannel 11 and te feather 11 1 and serving by reason of such engagement totransmitmotion from the shaft-section 8- to the shaft-section s, is designatedin a general' I way by C, being formed with a channel 12, adapted toengage with the feather l t and a feather12, extending substantially atright angles to the channel 12 and adapted to engage with vthe channel11- in the head 10-.

Evidently when the parts areassembled, with their-respective channelsand feathers in engagement, the rotation of the shaft-section s will betransmitted to the shaft-section 8, even though the axes ofthe'twosections are not in line and even though such axes are disposedsomewhat at an angle to each other, the respective ribs during thisrotation slid ingto and he in the channels with which they engage. Inorder to prevent the accidental displacement of the coupling-piece Cfrom its proper position with relation to one of the heads with which itengages whenthe shaft-sections are disassembled, it is here combinedwith means for securing'it toone of said heads, although not in a mannerto prevent its proper working. In this case it is adapted to be securedto the head 10 by means of a screw 13, engaging with atapped opening insuch head, and the shaft-section s to which the head is afiixed,the-opening' in which the shank and head of the screw are located beingsufficiently large to permit the free and'necessary play of'thecoupling-piece.

of the head 10 of the coupling when the parts are assembled, whiletheouter radial face of the elongated bearing in the member C is also inclose relation with the radial face of the hub of the pullev P;

The frame B is in the illustrated construction shown provided with anannularexten? sion 6, encircling and substantially concentric with theshaft, while in the vertical wall of this extension rearward of thecoupling there is a bearing for the sections of the shaft. The end orradial face of thebearing in the wall I) being in close relation to theradial face of the head 10 prevents, therefore,

when the coupling is closely assembled, the axial displacement of themain section 8 of the driving-shaft.

7 There is also shown, combined with t e present driving mechanism,means a lubricating medium to the various ournalbearings supporting thedriving-shaft and. for circulating such lubricant in a closed circuit inwhich such bearing portions are included. As a means for circulating thelu bricating medium a suitable form of centrifin theen wall member 0extends through 1n the member the lower or base ugal or other pump maybe used, preferabl driven from one or the other of the shaft-sections 8or s. In the construction and organization herein ment, being preventedfrom rotation by any suitable means, the 'form thereof herein showncomprising a lug or finger 14, extending from the casing of the pump andextending when into a recess between 1n proper position osses orprojections 15 15 on of the frame B; The pump illustrated is situatedbetween the shaft-bearings in the rear wall I) and the portion 4.

In order to make a convenient reservoir for receiving the drip from thevarious bearings, portion of the frame B is shown having-a floor with adepression, the sides of the lubricant-receptacle being formed by thecasing E. The suction-pipe 1601 the pump terminates adjacent to thebottom of such depression, while the discharge-pipe 17 from theump'communicates with a crosspipe 17, i fom which leaders or branchesextend to proper points for &c., into openings communicating with thevarious bearings. In the organization set forth this forced lubricationis directed to a plurality of journal-bearings, that for theshaft-bearing in the portion 4 havingan oilhole 18, immediately abovewhich the dis charge-pi e 18 terminates, while the bearing 1) of theframe extension I) has an oil-opening 19, with respect to which adischarge-pipe 19 is also properly located. The oil-hole 20 for thejournal-bearing in the and through a continuation of such opening C,thevtwo passages being in alinement whenthe member 0 is adjusted to itsproper position and'the horizontalfeeder 17 havin 1 above suc opemng.The oil-groove 20 in the journal-bearing in .the member C, with whichthe oil-passage therein communicates, preferably extends to andterminates in that radial face of themember Oagainst which the hub ofthe pulley P bears in order to Inbricate such surface. A The drip fromthe joint between the face of the hub and the contacting face ofthemember C is received for forcing shown the movable element; of thispump, the latter being designated by a fixed portion discharging theoil,

the extension 6 a discharge-opening situatedin a suitable channel v v 1nthe resent case formed in part b and in part by a ange 21. The drip inthis channel, being naturally thrown outward by centrifugal force towardthe bottom of the channel, is returned to the receptacle in the frame Bby means of a return-pipe 22, secured in a passage-way 21 in the member0 and communicating therethrough with the space below thecoupling-chamber, which has an opening 0' in its bottom surface, throughwhich the oil discharges into the receptacle. The outer end of thereceivingpipe 22 is curved around the axis of the driving-shaftconcentrically therewith and terminates in close proximity to the bottomof the channel W in a position above the driving-shaft to receive theoil in the channel thrown outward against the bottom surface thereof bycentrifugal force. The casing E, attached tothe frame B, serves not onlyto form an oil receptacle or reservoir, but also to inclose the variousparts of the head.
